so what is FTTB?
Prior to becoming nbn-ready, every address in the country is mapped by the nbn™ to determine the type of network technology used to service your address, with each technology being installed in its own unique way.
There is currently a mixture of seven core technolgy types that are used to install the nbn™ and FTTB (short for Fibre to the Basement) is one of these.
If you live in an apartment or similar building the fibre optic cable will lead to your building’s Main Distribution Frame (MDF). The MDF then connects to a wall socket in your unit via the building's internal cabling and this is known as Fibre to the Basement (FTTB).
excuse us while we get technical for a second
Get ready because things are about to get a little complicated.
The nbn has Points on Interconnect (POIs) around the country that connect to the wider internet. These tend to be located in the old telephone exchange building in each suburb. From these POIs a fibre optic cable connects to nbn nodes (purpose-built street cabinets) which are closer to your house. A copper cable (existing phone and internet wiring) then connects the node to your house.
If your household already connects to the internet through ADSL, there is a good chance you’ll end up with FTTN for your nbn connection type, as it utilises the existing internet infrastructure.
